5 vision of a device of the class mentioned which is of simple durable construction, desirable in use and eflicient in action, and

which can be manufactured and sold at a rea sonable cost.

The invention proposes the use of a' U- shaped tube consisting of an inner arm for being disposed on the inner side of a window sash and an outer arm. A stiff flexible cable is slidably mounted in the tube, and arranged for moving a window contact member. The window contact member-should be provided with a rubber squeegee and a moistener. The mner arm should be formed with a slot thru which a handle extends, said handle being connected with the cable for moving it.

It is pointed out that a person standing within a. room may place the device so that the inner arm is disposed on the inside of a win dow while the-outer arm extends around the contact member to move similarly. Thus the outer sides of the windows may be cleaned without the necessity of a person reaching the outside of the window. This arrangement would prevent the accidental falling of a person attempting to clean the outer sides of the window.

For further; comprehension of the invenof,.reference will be had to the following descrigtion and accompanying drawings, and to t e appended claims in which the various ticularly set forth.

Fig. 8 is a, perspective view of the top end of the rod for supporting the window contact member. L

Fig. 9 is a view similar to Fig. 3, but illustrating a modification. I The reference numeral 10 indicates generally a wall ofa room, provided with a window frame 11 having an inner sash 12 and an outer sash 13. A window cleaning device 14 is shown engaged about the outersash 13. This window cleaning device 14 consists of iron and having an inner arm 16 and an'outer arm 17 As seen in Fig. 1, the inner arm 16 a U-shaped tube 15, preferably of galvanized is disposed on the inner side of the sash 13,

while the outer arm 17 is disposed on the outer side of the-sash.

A flexible stifi cable 18,'preferably of brass is slidably arranged within the inner arm 16 and'extends the full length of this arm and around the bend of the U-shaped member. A cable handle 19 is attached onto the cable 18 and projects out of a slot 20 formed in the for the rod- 21. A set screw 23 projects from formed inthe outerarm 17. This set screw preventsthe rod 21 from turning but does I 7 not interfere with; the sliding of the rodan inturned top edge 22 forming a bearing novel features of the invention are moreparrodgl and Passes thru a second slot 24 -A window contact member 24 is attached on the extended'e'nd of the rod 21. An end cap 25 is threadedly'engaged on the free end of the inner arm 16 for closing the top of this arm. The rod 21 is provided with a front niche 26 and a-rear niche A set screw 28 engages thru a flange 2910f the windowcontact member 24' d one ofthese 16c.

niches for holding the member 24' in position.

The window contactmember 24 consists of a water receptacle 3O havinga plug openmg 31. A rubber squeegee 32is engaged in one side of the receptacle and a felt moistener 33 in the other side. Water within the receptacle may touch the rear side of the moistener 33.

In the modified form of the device illustrated in Fig. 9 the inner arm 16 is formed with a parallel slot extension 34 connected with the slot 20 by a transverse slot connector 35, and a second parallel slot extension 36 connected with the slot 20 by a second transverse slot connector 37. The slots 34 and 35 are of diiferent lengths and at different height positions relative to. the slot 20.

. In operation of the device it is placed upon a-window sash so that the inner arm is disposed on the inside of the sash and the outer arm on the outside. Then the cable handle 19 is moved up and down in the slot 20. This motion is transmitted by the flexible cable 18 to the rod 21 and to the window contact member 24'. This contact member is first arranged with the moistener 33 adjacent the window. Obviously. the window contact member moves up and down so that the outside of the Window pane is wetted. The device is then lifted into the room and the window contact member 24 turned around so that the rubber squeegee is next disposed on the outer side of the window pane. When the device is again applied upon thewindow sash motion of the handle will cause the rubber squeegee to dry the outside of the window ane. 1

The handle 19 may be passed thru the transverse slot 35 and then into the slot extension 34. In this condition the amplitude of the window contact member will be determined by the top and bottom extremities of this slot. In a similar way the handle 19 could be passed thru the slot connector 37 into the slot extenson 36. In this condition the amplitudeof the window contact member will be deterthis slot. Thisis of particular advantage for cable slidable within the U-shaped tube and of a length e ual to the U-bend and the inner arm, a win ow contact member above the free end of the outer arm and connected by a rod with the end of the cable directed towards the outer arm, the said inner arm being formed with longitudinal parallel slots of different lengths connected with each other by transverse slots, and a handle for moving "the cable extending thru one of said slots and rod with the end of the cable directed towards the outer arm, the said inner arm being formed with longitudinal parallel slots of different lengths connected with each other by transverse slots, and a handle for moving the cable extending thru one of said slots and movable into any of the slots for limiting the amount of motion of the cable, said handle being attached on the cable and movable transversely into any of the longitudinal slots by a twist of the cable.

3. A window cleaning device, comprising a U-shaped tube consisting of an inner arm for being disposed on the inner side of a window, and an outer arm for being disposed on the outer side of a window, a flexible cable within the tube and of a length equal to the U-bend and the inner arm, and slidably engaged in these parts, a handle attached on thecable and extending out of a slot in the inner arm, and engageable in parallel slots formed in the inner arm, and of different lengths, a rod attached on the cable and extending out of the outer arm, and a window contact member attached on the extended and of the rod.

In testimony whereof I have afiixed my signature.
